METAL-Box TOP.

Specification of Letters Patent.

Application filed May 8. 1908. Serial No. 431,682.

' To all whom it may concern:

Be it known that I, ()r'ro lineman, a citizen of the United States, residing at Gopiague, in the county of Suffolk and State of New York, have invented new and useful Improvements in Metal-Box Tops, of which the following is a specification.

This invention relates to box tops, and more especially to the caps for metal cans; and its object is to provide the can and top .with such means as willafiord ready application of the top to the can and instant release of the top from the can for its remoi'al, and at the same time to secure an air-tight or water tight closure, as will be more fully explained in the following specification, set forth in the claims and illustrated in the drawings, where:

Figure 1 is a side elevation of a can or tin box illustrating the invention. Fig. 2 is a similar view showing the cap removed. Fig. 3 is a plan view of the locking means at the top of the can. Fig. 4: is a sectional view of same. Figs- 5, 6 and 7 illustrate the process of making the locking means. Figs. 8 and 9 show a modified construction of the top.

In the construction of this can or box the upper edge of the open end is provided with overhanging cam faces 10 which may be of any desired number; for convenience of I illustration four are shown. At the upper faces of the cams the diameter of the edge is'decreascdas at 11 to allow the lugs 12- which are formed on the top 13 to pass down the reduced portion 14'of the top edge so that they may come in the path of the cam faces. When thus disposed on the upper end of the box, the top is loosely fitted but by turning the same in the direction of the arrow in Fig. 2 the lugs are brought into engagement. with the inclined surfaces of the cams and the top is forced downward bringing'its under side into close. engage-. ment with the upper edge 15 of the box. In order to make a,thoroughly tight closure a washer or disk ofpaper or cork may be inserted-in the topfso as to beforced down upon the edge of the box-wand form an air tight packing In the manufacture of this improved top and closure thebo'x is made in the ordinary manner of-a band or sheet of metal seamed along its length and having a bottom.

Within the upper open end of the box is secured a ring 17 carrying the cam faces 10 Patented Jan. 3, 1911.

ring with its cain facesis best shown in V Figs. 0, 6 and 7. From a disk of sheet metal is struck with one operation the form shown in Fig. 5 the main portion 16 of the disk remaining in its original condition and having the sides or ring 17 rising therefrom; with the same operation the flange 18 is also formedand the blank in this condition is ready for the next operation. In Fig. 6 is shown the next operation where it will be seen that from the flange 18 is cut the cam faces 10 although they remain in their horizontal position. The third and last operation results in the condition shown in Fig. 7 where the bottom 16 has been cut out and the cam faces have been given their vertical position and this part of the box is given the form of a ring whose outer diameter is about equal to the inside of .the box it is to accompany and it is fitted within the upper end of the box and soldered.

engagement with the inclined surfaces of i the cam, the said wall of the said top or lid will lie substantially iiush with the side wall of the said can or box;

It is obvious that: I do'not confine myself to the exact shape .or number of the cam faces shown but itis desirable that the lugs shall equal them. I What I claim as new and desire to secure .by Letters Patent is: Y

1. The combination with a can body and lid, of. 'a neckfor said can body, comprising a ring formed as an entirety from a single piece of sheet metal, said ring being cut into at its upper edge to provide a. plurality of circumferentially arranged laterally bent flanges relative to said ring, said flanges being down-turned exteriorly of 'said ring concentricallywith respect thereto and having lower inclined imam edges whereby on engaging the lid with the neck, it will be secured upon the ca'n.

2. A metal can or receptacle having a neck portion with cuts therein at its upper edge and bent to provide out-turned spaced ram flanges at the free edge of said neck, 5 each flange having a horizontally disposed body portion, and a depending ortion having a lower inclined edge, said ing arranged exteriorly of the can substantially flush with the outer side wall thereof,

10 and a cap adapted to inclose wholly the flanges bein presence of two witnesses.
